Crusader Kings 2 is a fantabulous grand strategy game: a historical sandbox where every emperor, ruler and vassal can become your playthings. Paradox Interactive has outdone themselves in terms of both quality and quantity (more details in our 9/10 review), bolstered by plenty of DLC packs over the last few months. Though we've occasionally seen it cheaper (Impulse's short surprise deal expired ages ago), Gamefly are currently the cheapest retailer around with a saving of over £5.
